The 770 is a cost effective and compact standalone GSM Beacon vehicle tracking and recovery system that could also be employed as a backup to existing GSM / GPS tracking systems. The unit is pre-programmed to a “sleep” mode where there is no GSM communication and is therefore un-detectable from GSM scanners. The unit will periodically wake up and communicate with the control centre and revert back to “sleep” mode. If the vehicle was stolen or hijacked in the “sleep” period the message from the control centre will force it to stay awake and activate the onboard 868 MHz beacon transmitter. The vehicle can then be located by means of a direction finding (DF) antenna and receiver using the most recent GSM Triangulation co-ordinates.
